What I claim, is: f

l. A tubular drum comprising a plurality of segmental sheets having longitudinal flanges formed therefrom along each edge, said flanges being secured together to form beaters on the outer 'surface of the drum, and means at the ends of the drum on `Which the sheets are mounted to permit passage of air through the drum.

2. A drum comprising a plurality of segmental perforatedsheets having longitudinal* flanges formed therefrom along each edge, said flanges being secured togethery to form beaters on the outer surface of the drum, spider arms at the ends of the drum on which the sheetsare mounted, and pins mountedr on the sheetsbetween the flanges.

3. `A drum comprising a plurality of segmental sheets having longitudinal flanges yformed ltherefrom along each edge, said y flanges .being secured together to form beaters on the outer surface of the drum, and spiders at the ends of the drum on Which the sheets arel mounted, the sheets having air emitting perforations and the ends of theA drum being open for admitting air.`

Ll. A drum Comprising a plurality of segmental sheets havinO' longitudinal flanges formed therefrom along each edge, said flanges being secured together to formvbeaters on the outer surface of the drum,-spiders at the ends of the drum on which the sheets are mounted, the sheets having air emitting perforations and the ends of the drum being open for admitting air, and means for drawing air into the drum through its open ends.

`5. A drum comprising a plurality of segmental sheets, spiders including supports on which saidy sheets 'are fastened and arms forming fan blades set to draw air into the drum as it revolves, said sheets having air emitting openings,` and longitudinal beaters on the sheets contiguous to the air openings for deectingthe emitted air.

6, A drum comprisinga plurality of elongated segmental sheets having` flanges bent outward along theiry parallel edges, means for securing the flanges together, spiders including rings on which the sheets are mounted and radial arms in the form of. fan

blades, and means vfor fastening the sheets for'securing the flanges together, spiders in,-V

cluding rings on which the sheets are mounted and radial arms in the form of fan blades, means for fastening the sheets on the rings of the spiders, and pins fastened to the sheets between the flanges, each sheet having a row of perforations contiguous to one of its flanges for emitting air.

8. A drum comprising a cylindrical member open at each end and having a plurality of air emitting openingsin its Walls, fan blades mounted Within the open ends of the cylindrical member, and screens mounted Within the said memberv for intercepting the passage of lint, fibres and trash to the air emitting openings.

9. A drum comprising a cylindrical member open at each end and havinga plurality of air emitting openings in its Walls, of spiders mounted Within each end of the member and each including a ring engaging the member and fan blades carried Within the ring, and screens mounted within the ends of the member contiguous Ito said spiders for intercepting the passage of lint, fibres and trash to the air emitting openings.

ln testimony whereof I alli); my signature.
